Abstract

The purpose of this paper is to map the level of dengue hemorrhagic fever vulnerability using the Geographic Information System (GIS) in Lubuklinggau. This type of research uses quantitative methods and is carried out in the administrative area of ​​Lubuklinggau City, South Sumatra Province. The type of data used is secondary data obtained from relevant agencies and remote sensing data, there are four input data; the incidence of dengue hemorrhagic fever, temperature, population density, and vegetation density. Data analysis techniques using data analysis using scoring methods with Geographic Information Systems (GIS). The results obtained that the level of DHF vulnerability based on spatial analysis in Lubuklinggau City in 2016 were divided into three classes, namely areas with low vulnerability levels of 5.928,06 ha or 16%, areas with moderate vulnerability levels of 22.903,80 ha or 62%, and areas with a high level of vulnerability are 7.917,97 or 22%. So, the level of vulnerability to dengue disease, the results obtained that the City of Lubuklinggau is at a moderate level of vulnerability.

Abstract

The District of Besuki is one of the regions in Tulungagung Regency which has karst morphology. The high quantity of rainfall and unpredictable weather in the karst area can increase the risk of natural disasters such as floods and landslides. The technology of making biopore infiltration holes can be used as one of the solutions in flood disaster mitigation efforts. These infiltration holes generally used in dense areas of settlements or regions that have minimal water catchment areas. This study aims to determine the use of biopore to prevent flood in Gambiran, Besole Village, district of Besuki, Tulungagung Regency. This type of research is an experiment. The measure water absorption was utilizing a variety of tools such as double-ring infiltrometer, stopwatch, special ruler measuring the water speed. The results showed that the use of biopore is effective in reducing the impact of flooding in karst topographic areas, especially in Gambiran Hamlet, Besole Village, Besuki district, Tulungagung Regency. This was proven by experiments conducted by making comparisons between treated soils with biopore infiltration holes and soils without any treatment. During one month, with four times the treatment of water absorption can increase more than doubled. If the point without treatment is only able to absorb water as deep as 23 cm / 30 minutes or an average of 0.7 cm/minute, then the treatment point can absorb water as deep as 57cm / 30 minutes or with an average value of 1.9 / minute. With the increasing absorption of groundwater, the use of biopore infiltration holes can reduce the impact of flooding in karst areas, especially in Gambiran Village Besole Village Besuki District Besuki Tulungagung Regency.
